could you post a pic with the black dots? i haven't got deen, so i can't replicate this script.

i see no immediate probs with it.

i'd try it in yuy2 and see if it works

[Krizzz989]

ok here's the problem http://dotsarelame.netfirms.com/

it doesn't matter if deen is there or not. thanks for the suggestion, but the problem remains.

I've yet to have good luck doing ANYTHING to AVI sources.

[Ejoc]

I get a warning on frame 1 of that avi:

Warning: nothing to output bframe decoder lag

[Asrial]

Go to frame 2 and then back to frame 1 and all is well :P

@Krizzz989,

What happens if you leave:

1) deen out

2) resizing out

3) deinterlacing out

@Ejoc,

That's normal for a XviD clip. I forgot the reason (something to do with b-frames), but you can find it in the XviD forum somewhere.

@Asrial,

Provide more info. We can't help you like this. Do you have the necessary codecs installed (like huffyuv, DivX5, etc.). Do you get error messages?

[Dreassica]

U have Trellis Quant enabled in xvid maybe?

[Krizzz989]

even if i did, i'm using mod16.
and when viewing my source (which is actually DV) through vdubmod using the avs, the dots are there...

[sh0dan]

It looks like deinterlacing (bob) artifacts. I believe Don refers to this as "dot crawl". Try kerneldeint - with a lower threshold (4-7).

(a threshold of 4-7 was leaving dots still)

thanks for the help everyone, getting close to a solution :)

Kerneldint is probably the best there is for anime/cartoons.

There is also FieldDeinterlace(blend=true), but it will have significant blending. "blend=false" will reintroduce the dot crawl.

[Krizzz989]

i was looking to decimate for 23.97 output.Telecide(guide=1,0,post=1,hints=true)
kerneldeint(order=0,threshold=20).Decimate(5)

and

b = dgbob(order=0, mode=1)
kerneldeint(order=0)are not giving me good results (blending),

andassumebff().smartdecimate() gives a very odd shimmering effect

well this seems to work. thanks for the help everyone :)

EDIT: but it leaves interlacing artifacts :(
